WILLIAM L. HESS, OF BELLE PLAINE, IOWA.

COMBINED STOVE-PIPE DRUM, SHELF, AND DAMPER.

SPECIFICATION forming part of Letters Patent No. 272,048, dated February 13, 1883. Application'filcd October 3, 1882. (No model.)

To all whom it may concern Be it known that I, WILLIAM L. HEss, a citizen oi the United States of America, residing at Belle Plaine, in the county of Benton and State of Iowa, have invented certain new and useful I mproveme-ntsin Stove-Pipe Drum, Shelf, and Damper Combined; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

In the drawings, Figure 1 is a top plan view of my improved stove-pipe shelf, the cover of said shelf being removed to show the inner conical partition. Fig. 2 is a transverse vertical section taken on the line a; x of Fig. 1; and Fig. 3 is a similar section taken on the line 3 3 to show the smoke-space in the tubular sliding valve.

Similar letters of reference in the several drawings denote similar parts. a

This invention relates to certain improvements upon Letters Patent numbered 201L570, said patent relating toimprovements in stovepipe shelves or heaters granted to me J une 4, 1878. In, said patent I employed a flat horizontal partition in connection with a drum or cylinder, the stovepipe proper extending through said cylinder, and having openings, being opened or closed by a sliding tubular valve. In the present instance I employ a similar drum or cylinder divided into two chambers by a conical diaphragm or partition, through which the heat and smoke ascends, the central of which perforations is opened or closed by a damper operated from the outside of the drum or cylinder. 1 also employ atubular valve placed in the stove-pipe above the drum or cylinder, and so arranged as to slide downward to and rest upon the top of the dia phragm or partition above the central perforation therein. In my former patent, when the tubular valve was down the ascending heat and smoke passed upward through the stovepipe without passing into either of the chambers in the drum or cylinder. In the present invention the ascending smoke and heat pass into and through the chambersof the drum or cylinder, and thence escape into the pipe, when the tubular valve is down as well as when said valve is up, proper vents being made in said valve to effect this purpose. found by experiment that a partition having a conical form or shape, as herein described, gives better results than one made in the form described in my former patentthat is, flatinasmuch as the ascending heat and smoke (when the central damper is closed) first come in contact with the upper part or apex of the diaphragm, and thence, in order to escape from the lower chamber, must return backward and downward to the vents or perforations made in said diaphragm near its outer edges. By this construction heat remains much longer and is more intense in the chambers of the present improved pipe-shelf than in the corresponding chambers of the pipe-shelf shown and described in the patent above referred to.

Referring to the drawings, A represents a drum or cylinder, the lower portion of which tapers downward and inward, as shown. ihe lower portion of the drum A is provided with; a short section of pipe, A, adapted to tit upon or in the pipe above the stove.

A represents the cover of the drumor cylinder, said cover being movable and provided with a short section ot'pipe, A, the lower end or edge of which is flush with the under surface of the cover.

B representsa diaphragm or partition, made conical as shown, and provided with apertures b b, the central one of which, I), is circular in form and of the same diameter as the PIPGSBO- tions, and is provided with a short section of pipe, B, within which is placed an ordinary damper, B operated by a rod,b that extends to the outside of the drum or cylinder. The apertures I) are arranged around the outer edge of the diaphragm B, as shown.

0 represents a tubular sliding valve placed in the pipe-section A and operated by a stud, c, that moves up and down in a bayonet-slot, c, in the pipe. The lower edge or end of the tubular valve 0, is provided with openings c,

I have through which, when said tubular valve is 7 down, the smoke escapes from the chambers.

D represents a frame attached by eyes d to one side or edge of the cover A and serves to give an additional bearing-surface to the shelf IOO 2 crane-re forlarge article's. TheframeD may be dropped downward against the side of the drum, in which position the lower partsor arms, r1 project outwardly and serve to hang articles, as towels, dish-cloths, 850.

I attach importance to thediaphragm having asection of pipe, B, in lieu of a pipe which extends entirely through the shelf. My construction affordsa proper inclosure for the damper, and enables me to quickly and conveniently separate the shelf into its several parts for cleaning, repairs, transportation,storage, 850.

I am aware that adiaphragrn with perforated edges is not broadly new.

Having thusfnlly described my invention, What I claim, and desire to secure by Letters Patent, is-

1. In a stove-pipe shelf, the combination of cover A with the conical diaphragm or parti-- tion B, having perforations b b-, and pipe-section B, substantially as and for the purpose set forth.

2. In a stove-pipe shelf, the combination of the drum or cylinder A, having the removable cover A, and conical perforated diaphragm B, with the tubular valve 0, having openings 0 at its lower edge or end, and held and moved up and clown in the pipe-section A by the stud c, substantially as described.

In testimony whereof I affix my signaturein presence of two witnesses.

WILLIAM L. HESS.
